I went to pcpartpicker and came up with a dirt-cheap pc build. It's less than $550, and it would stomp anything you could buy pre-built under $1,000. It could even be upgraded with any newer $200 graphics card for 1080p or 1440p gaming, or for smoother playback on Netflix if you watch at 4K. If someone just surfs the web, posts in a forum, and watches youtube videos and Netflix or Hulu, this build would kill it for several years down the road. And it is mini-itx, so it's a way smaller machine.
